    • There are provided laminated bodies or laminated body-containing windows, which comprise isotropic aqueous solutions obtained by dissolving a water-soluble polysaccharide derivative having nonionic amphipathic functional groups in an aqueous medium composed of water and an amphipathic substance, laminated between plates that are at least partially transparent and allow direct vision of the isotropic aqueous solutions, wherein there are added to the isotropic aqueous solutions in appropriate amounts ultraviolet absorbers comprising nonionic or ionic benzophenone derivatives or benzotriazole derivatives which are highly weather resistant and uniformly dissolve in the isotropic aqueous solutions. The isotropic aqueous solutions are transparent and become opaque upon irradiation with light, and exhibit stable reversible change, in order to provide vastly improved weather resistance to the laminated bodies against exposure to sunlight rays over prolonged periods of time.
    • 提供了层叠体或层叠体的窗口,其包括通过将具有非离子两性官能团的水溶性多糖衍生物溶解在由水和两亲物质组成的水性介质中而获得的各向同性水溶液,所述水性介质层叠在板之间,至少 部分透明并且允许各向同性水溶液的直接视觉,其中以各种各向同性水溶液适量添加紫外线吸收剂,其包含耐高度耐候且均匀溶于各向同性水溶液中的非离子或离子二苯甲酮衍生物或苯并三唑衍生物。 各向同性水溶液是透明的,并且在用光照射时变得不透明,并且表现出稳定的可逆变化,以便在长时间的时间内对层叠体提供大大改善的耐候性,防止阳光照射。
